Write the equation of the line in slope-intercept form that passes through the point (2,-5) and has slope of -1

y=-x-3

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=-1(x-2)

y+5=-(x-2)

y+5=-x+2

y=-x+2-5

y=-x-3

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
